3-WAY, BALANCED VALVES
7. Instale el actuador invirtiendo el procedimiento del punto
(2).
PUESTA EN SERVICIO DEL SISTEMA DE AGUA
Para que el producto funcione sin problemas, una buena
práctica de instalación debe incluir el lavado inicial del
sistema, el tratamiento químico del agua y el uso de
filtro(s) fino(s).
Ponga la palanca manual del actuador VC (Fig. 6) en posición
de apertura (mitad del recorrido) para permitir el lavado inicial
del sistema con el actuador montado. Esta operación se debe
hacer sin alimentación elétrica.

Electrical installation, cables and related
accessories must comply with local laws directives
and competent authorities.

IMPORTANT
— Each 3-wire (SPDT) actuator must have individual
SPDT controller.
— On 24V systems, never jumper the valve coil
terminals, even temporarily. This may damage the
thermostat.
— The cable version must be used for mixed line voltage
and 24 Vac (Safety Extra Low Voltage) applications.
For controller action and electrical terminations, see Tables A
and B.
Figs. 7 and 8 show wiring diagrams as printed on product label
for the Cable Model and Molex™ Model for use with SPDT
controller.
Figs. 9 and 10 show wiring connections with SPDT and SPST
controllers. Port "A" open and closed denote valve open and
closed positions respectively. On auxiliary switch models,
terminal 4 (grey wire) contact makes at the end of the port A
opening stroke. On Molex™ connector models, valve and
auxiliary switch voltage must be the same to meet approval
requirement.

COLLEGAMENTI ELETTRICI
ATTENZIONE
L'installazione elettrica, come pure i cavi ed i
relativi accessori devono essere conformi alle
direttive ce ed alle normative cei.
IMPORTANTE:
— Ciascun attuatore per comando a 3 fili (SPDT) deve
essere comandato dal contatto SPDT di un solo
regolatore.
— Nei modelli a 24V, non cortocircuitare, neanche
temporaneamente, la bobina del motore. Potrebbe
danneggiarsi il termostato.
— Utilizzano una tensione differente tra motore e micro
ausiliario (es. 24V e 230V ca) è necessario utilizzare
la sola versione con cavo da 1 metro (Sicurezza a
bassa tensione).
Per l'azione del regolatore ed i morsetti elettrici riferirsi alle
tabelle A, B.
